Copper Alumina Welding Needle 18650 Battery Pack Welded Diameter 1.7/3.0MM
● Alumina brazing needle is suitable for spot welding between nickel strip, nickel-plated steel plate, coated steel strip and other materials in battery production. It is used to produce nickel gas batteries, nickel pot batteries, polymer batteries, lithium batteries and other batteries, spot welding connectors, batteries and extraction parts.
● Product name: aluminum oxide copper spot welding needle and bump welding needle
● Material: made in China, made in Taiwan, made in Japan and made in America.
● Needle type: eccentric flat head, eccentric ball head, concentric ball head, straight baseball head, straight stick, and other customization.
● The welding needles produced by our factory are all made of aluminum oxide and copper.
● Resistance welding material-nano alumina dispersion strengthened copper (alumina copper)
● Resistance welding material expert Nano-alumina dispersion strengthened copper referred to as (alumina copper) alumina copper-specially designed for spot welding of galvanized steel plate, nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
● Alumina copper material has the advantages of softening resistance, ablation resistance, long service life and high number of spot welding.
● The service life of the electrode is more than 5 times that of the common chromium, zirconium and copper, which reduces the downtime and grinding time of the electrode.
● The battery spot welder adopts the welding needle made of aluminum oxide and copper, which improves the efficiency of the automatic welding production line, and does not bond the electrode when welding the coated metal, which provides a terminal solution for the welding of galvanized steel plate, and is an indispensable electrode material for welding galvanized steel plate, nickel-plated plate, nickel tape, aluminum alloy, stainless steel, brass, etc.
● The softening temperature is as high as 930℃, which is higher than that of copper alloy, but lower than that of tungsten copper (1000℃).
● The electrical conductivity of alumina brazing needle is as high as 85%IACS, and its heat dissipation performance is between that of tungsten copper (220 W/m-k) and pure copper (390 W/m-k).
